chenglei updated HBASE-27433:
-----------------------------
Description: When compaction is failed,
{{DefaultMobStoreCompactor.performCompaction}} deletes the {{MobStoreFile}}
which is writing, but for {{OptimizedMode}},
{{DefaultMobStoreCompactor.performCompaction}} may create multiple
MobStoreFiles, if compaction is failed, all theses MobStoreFiles are useless
and should be deleted altogether. we should better not depend on
{{RSMobFileCleanerChore}} to clean them because it is mainly used for archive
already compacted {{MobStoreFile}}s. (was: When compaction is failed,
{{DefaultMobStoreCompactor.performCompaction}} deletes the {{MobStoreFile}}
which is writing, but for {{OptimizedMode}},
